STAGE 2 BANKROLL MATRIX · GRAND MARTINGALE · 150U / 1-SHOE

Grand Martingale (2x+1) — 150-Unit Bankroll & 1-Shoe (72-Hand) Risk-of-Ruin Matrix

Sequential profile M141-0 inspects Grand Martingale (2x+1) over a 1-shoe (72-hand) horizon with 150 units: sequential escalation (1-3-7-15-31-63-127, 7 steps) interacts with the 40-unit limit to inspects a 14.06% ruin rate and a stochastic stake-velocity of 6.03x. Every 8-deck hand remains statistically independent (45.86% Banker, 44.62% Player, 9.52% Tie), meaning progression sizing reshapes session variance without altering the house edge.

MATRIX CELL M141 · STOP-LOSS & STOP-WIN GEOMETRY

Grand Martingale 150u step-indexed cadence Across 72 Hands (M141)

Under configuration M141-1, deploying Grand Martingale with 150 base units over 72 resolved hands (1 shoes) verifies a drawdown-weighted survival-window: hitting the 40-unit house cap after 6 adverse steps drives a 14.06% stop-loss breach rate against a 41.53% chance of reaching the +38-unit target.

Sequential profile M141-2 tabulates Grand Martingale (2x+1) over a 1-shoe (72-hand) horizon with 150 units: multi-coup escalation (1-3-7-15-31-63-127, 7 steps) interacts with the 40-unit limit to audits a 14.06% ruin rate and a combinatorial cycle-span of 6.03x.

40u Ceiling Collisions & Grand Martingale Turnover (1 Shoes)

Under configuration M141-3, deploying Grand Martingale with 150 base units over 72 resolved hands (1 shoes) quantifies a finite-shoe progression-curve: hitting the 40-unit house cap after 6 adverse steps drives a 14.06% stop-loss breach rate against a 41.53% chance of reaching the +38-unit target.

Sequential profile M141-4 charts Grand Martingale (2x+1) over a 1-shoe (72-hand) horizon with 150 units: session-bounded escalation (1-3-7-15-31-63-127, 7 steps) interacts with the 40-unit limit to verifies a 14.06% ruin rate and a capital-bounded distribution of 6.03x.

  • Cell M141 rule: lock the -75u stop on your 150u Grand Martingale stack across 72 hands.
  • Matrix M141 maps 7.71u ($193) in house hold over 434u of Grand Martingale action.
  • Scoreboard check M141: Big Eye Boy, Small Road, and Cockroach Pig use red for repeating symmetry (step-indexed cadence) and blue for pattern breaks—never for Banker or Player.
Table Reality Check

Myth vs. Truth

MythBringing 150 units to a 1-shoe session lets Grand Martingale (2x+1) overcome the 1.058% Banker house edge.
TruthNo bankroll size alters per-hand expectation: over 72 hands, Grand Martingale generates 434u in action, 7.71u in expected loss, and a 14.06% stop-loss ruin rate.
MythDerived road colors on the scoreboard tell Grand Martingale bettors whether Banker (red) or Player (blue) is due during a 72-hand run.
TruthOn Big Eye Boy, Small Road, and Cockroach Pig, red indicates repeating column structure and blue indicates breaking structure; neither color represents Banker or Player.
